Quartz pseudomorph after Epidote with Hematite and Goethite (ex Kay Robertson Collection)

Item Description

A very cool US pseudomorph of these classic specimens from Bessemer Ridge featuring Hematite and Goethite which have replaced a preexisting crystal of Epidote and then later coated by sparkling white Quartz. The original monoclinc prismatic form of the Epidote crystal is still beautifully preserved, and the piece is a superb example of these beloved and rare pseudomorphs. These are the kind of specimens that you can't get on the market anymore, you can only find them in old collections like this. Ex Kay Robertson Collection (#10203). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record). A beautiful and attractive old-timer from this lesser known locality.
